Question 1

A BIOMED technician notices that medical device telemetry data is dropping packets on the hospital Wi-Fi. Which QoS mechanism should be prioritized to ensure reliable transmission?

Accepted Answer

Weighted Fair Queuing (WFQ) with medical traffic class

Answer

Weighted Fair Queuing assigns higher priority to critical medical traffic classes, reducing dropped packets for telemetry.

Question 2

Under HIPAA's Security Rule, which control specifically addresses ensuring that ePHI transmitted over a network cannot be improperly modified without detection?

Accepted Answer

Transmission integrity

Answer

Transmission integrity controls verify that ePHI is not altered or destroyed in an unauthorized manner during network transmission.

Question 3

A hospital wants to segment its biomedical device network from the administrative network. Which technology accomplishes this at Layer 2?

Accepted Answer

VLAN (Virtual LAN)

Answer

VLANs logically segment networks at Layer 2 (Data Link), isolating biomedical device traffic from administrative systems.

Question 4

Which encryption protocol is recommended by NIST for securing data transmitted between medical devices and hospital servers in 2024?

Accepted Answer

TLS 1.2 or higher

Answer

NIST recommends TLS 1.2 or TLS 1.3 for securing data in transit; older protocols like SSL 3.0 and WEP are deprecated.

Question 5

A biomedical device is assigned a static IP of 192.168.10.50/24. What is the broadcast address for this subnet?

Accepted Answer

192.168.10.255

Answer

For a /24 subnet, the broadcast address is the last address in the range — 192.168.10.255.
